A characterization of strongly chordal graphs

Discrete Mathematics, 1998
AbstractIn this paper, we present a simple charactrization of strongly chordal graphs. A chordal graph is strongly chordal if and only if every cycle on six or more vertices has an induced triangle with exactly two edges of the triangle as the chords of the cycle.

Modeling and Measuring the Chart Communication Recall Process

Computer Graphics Forum, EarlyView.
Abstract Understanding memory in the context of data visualizations is paramount for effective design. While immediate clarity in a visualization is crucial, retention of its information determines its long‐term impact. While extensive research has underscored the elements enhancing visualization memorability, a limited body of work has delved into ...

Forbidden subgraphs of TI-power graphs of finite groups

Open Mathematics
Given a finite group GG with identity ee, the TI-power graph (trivial intersection power graph) defined on GG, denoted by Γ(G)\Gamma \left(G), is an undirected graph with vertex set GG where distinct vertices aa and bb are adjacent if ⟨a⟩∩⟨b⟩={e}\langle ...

Component graphs of vector spaces and zero-divisor graphs of ordered sets

AKCE International Journal of Graphs and Combinatorics
In this paper, nonzero component graphs and nonzero component union graphs of finite-dimensional vector spaces are studied using the zero-divisor graph of a specially constructed 0–1-distributive lattice and the zero-divisor graph of rings.

Multipla: Multiscale Pangenomic Locus Analysis

Computer Graphics Forum, EarlyView.
Abstract Comparing gene organization across genomic sequences reveals insights into evolutionary and functional diversity among different organisms and varieties. Performing this task across many sequences, such as from a pangenome, is challenging because of the scale, the density of information, and the inherent variation. Often, analyses are centered

Finite groups whose coprime graph is split, threshold, chordal, or a cograph [PDF]

Proceedings of the Estonian Academy of Sciences
Given a finite group G, the coprime graph of G, denoted by Γ(G), is defined as an undirected graph with the vertex set G, and for distinct x, y ∈ G, x is adjacent to y if and only if (o(x), o(y)) = 1, where o(x) and o(y) are the orders of x and y ...

Nodes, Edges, and Artistic Wedges: A Survey on Network Visualization in Art History

Computer Graphics Forum, EarlyView.
Abstract Art history traditionally relies on qualitative methods. However, the increasing availability of digitized archives has opened new possibilities for research by integrating visual analytics. This survey presents a comprehensive review of the intersection between art history and visual analytics, focusing on network visualization and how it ...

Ovarian Endometrioma Disrupts Oocyte‐Cumulus Communication and Mitochondrial Function, With Melatonin Mitigating the Effects

Cell Proliferation, Volume 58, Issue 4, April 2025.
Diagram illustrating the impact of OEM on oocyte‐cumulus communication, showing reduced TZPs, mitochondrial dysfunction, increased oxidative stress, DNA damage, and apoptosis. Melatonin (MLT) treatment improves communication, enhances mitochondrial function, reduces DNA damage, and restores oocyte quality, offering insights into potential therapeutic ...

Strongly chordal and chordal bipartite graphs are sandwich monotone

Journal of Combinatorial Optimization, 2009
A graph class is sandwich monotone if, for every pair of its graphs G 1=(V,E 1) and G 2=(V,E 2) with E 1?E 2, there is an ordering e 1,?,e k of the edges in E 2?E 1 such that G=(V,E 1?{e 1,?,e i }) belongs to the class for every i between 1 and k. In this paper we show that strongly chordal graphs and chordal bipartite graphs are sandwich monotone ...

Cell type mapping of mild malformations of cortical development with oligodendroglial hyperplasia in epilepsy using single‐nucleus multiomics

Epilepsia, EarlyView.
Abstract Objective Mild malformations of cortical development with oligodendroglial hyperplasia in epilepsy (MOGHE) are brain lesions associated with focal epilepsy and characterized by increased oligodendroglial density, heterotopic neurons, and hypomyelination in the white matter.
